Product description

Control Techniques UNI3403 is a universal frequency inverter from the Unidrive Classic product range. The complete identification number denotes the frame size 3 version for a three-phase 380–480 V AC ±10 % mains connection and a mains frequency of 48–62 Hz. The manufacturer documentation specifies rated power of 22 kW or 30 hp. Continuous output current is listed by switching frequency at 40 °C: 46 A at 3/4.5 kHz, 40 A at 6 kHz, 32 A at 9 kHz and 26.6 A at 12 kHz. On the input side, 40 A is documented as typical input current and 53 A as maximum continuous input current. Control modes include open loop, closed loop and servo. The unit uses forced ventilation. Degree of protection depends on the documented mounting arrangement and is listed as IP00, IP10 or IP40, respectively NEMA 1. The EMC filter is external and optional. These data describe the electrical, thermal and mechanical version of the exact variant. Control Techniques UNI3403 is 368 mm wide, 375 mm high and 260 mm deep. Complete external dimensions are therefore 368 × 375 × 260 mm in width × height × depth order. Documented weight is 22 kg. Dimensions and weight refer to the individual frequency inverter without shipping packaging. Manufacturer, product range, complete identification number, frame size, mains connection, mains frequency, rated power, output and input currents, control modes, cooling, protection ratings, filter version, external dimensions and weight form the technical variant data set. The assignment of current values to their respective switching frequencies is preserved in both table and description. The specification table concludes with Dimensions and Weight.

Control Techniques UNI3403 The item supplied will have the stated manufacturer or type number and the stated condition category. Serial number, manufacturing date, labels, colour, packaging and normal signs of use or storage may differ.
